Abstract

A method of transmitting data from a node, such as a session node including any network node, located in a first network to one of a plurality of devices located in a second network, said method comprising; determining that another device connected to the node is located in the second network; transmitting from the node to the other device located in the second network a message addressed to the one of said plurality of devices via the connection between the node and the other device; and forwarding the message from the other device to the one of said plurality of devices via a connection established within the second network.
